With the future LTE auction for TV white spacesat 600 MHz, there is a strong need for efficient handset antennasoperating at very low frequencies. This paper proposes a tunableantenna design for the low bands of LTE. In this design, not onlythe antenna is tuned but also the resonance of the board, thanksto using a tunable parasitic. The resulting dual-resonant antennaexhibits a peak total efficiency of -4 dB at 600 MHz.
